Gob-side entry retaining sealing thin spraying material for mining flexible membrane support technology and preparation method thereof
The invention discloses a mining flexible membrane support technology gob-side entry retaining sealing thin spraying material and a preparation method thereof. The mining flexible membrane support technology gob-side entry retaining sealing thin spraying material comprises a component A and a component B, the component A comprises the following components in percentage by weight: 30%-40% of white Portland cement, 48%-58% of quartz powder, 5%-10% of a flame retardant, 0.3%-1% of a thixotropic agent, 0.05%-0.2% of a water-retaining agent and 0.4%-1% of an early strength agent; and the component B comprises the following components in percentage by weight: 85%-95% of styrene-acrylic emulsion, 0.2%-0.5% of a defoaming agent, 0.2%-0.5% of a wetting agent and 5%-15% of water. When in use, the component A and the component B are uniformly stirred, and then spraying is performed. The thin spraying material disclosed by the invention has the functions of fire prevention, air insulation and air leakage stoppage, is strong in adhesive force, not easy to crack and good in leakproofness, and can be used as a gob-side entry retaining sealing material for a coal mine flexible film support process.
本发明公开了一种矿用柔膜支护工艺沿空留巷封闭薄喷材料及制备方法，包括A组分和B组分；所述A组分包括重量百分比为30％～40％的白色硅酸盐水泥、48％～58％的石英粉、5％～10％的阻燃剂、0.3％～1％的触变剂、0.05％～0.2％的保水剂以及0.4％～1％的早强剂；所述B组分包括重量百分比为85％～95％的苯丙乳液，0.2％～0.5％的消泡剂，0.2％～0.5％的润湿剂以及5％～15％的水。使用时，先将A组分和B组分搅拌均匀，然后进行喷涂。本发明所述的薄喷材料具有防火、隔气、堵漏风功能，薄喷材料附着力强、不易开裂、密闭性好，可作为煤矿柔膜支护工艺沿空留巷封闭材料使用。
